AMD Comments On XvBA Video Situation

Phoronix: AMD Comments On XvBA Video Situation

Last week there were XBMC developers that wrote a public message on Phoronix about AMD's problems with video playback acceleration using their Catalyst Linux driver. The developers called AMD out on their shortcomings and now today there's a response out of AMD...

"Everytime we try to get into official contact, we are told that AMD was working on it and everything was nearly done. We are hearing this for approximately half a year now from AMD, but were never given a timeline...Everytime we try to get into official contact, we are told that AMD was working on it and everything was nearly done.

for the zillion time plz fragging educate yourself before let crap run out of your mouth LOL.

* first remember that in 2007 we had basically nothing in the graphics side aka Xfree86, some very outdated/rudimentary DRI plataform and basically no memory management in kernel for the GPU and mesa 6 was GLX 1.4 at his prime.

* devs don't have 5 years working on radeon drivers, they have 5 years rewriting/re engineering the entire linux graphic stack (kernel/ttm/drm/dri/wayland/gallium/mesa/Xorg/cairo/etc) and when they can, they go to the drivers cuz most of the time at least until recently many driver functions are missing cuz the stack still need work for that specific function to work in the driver.

if still you don't get it is like pass from windoze 95(close to the old linux stack) graphic stack to windoze 7 graphics directly.

so another way to see it is linux community has taken 5 years to get close to what microsoft have done in at least 12 years

That remains to be seen. The fact that it is already implemented for a while could also mean that just the PCS key is needed for the previous (HD 400 supported) drivers.

What bugs me though, is that support for MPEG-2 VLD, MPEG-4 Part 2 and H.264 Level 5.1 has already been implemented for some time but, what appears to be, no effort has been made to finish and/or enable it. Such a waste, it would have made quite some people happy.

You're mostly right.
First, cairo has nothing to do with it
and 5 years to go to windows 7 comparable graphics.. Nope, sorry. The oss driver state is still quite horrible but it works and usually works better then the AMD drivers in terms of stability. However, in performance, power management and amount of noise produced it's still _far_ from being usable. But they are getting very close to good working drivers. I'd say probably about 2 more years before it's really in a good working shape.

If you want to compare it against windows then i'd say we are at the point where windows vista RC was released with the massive graphic driver issues

and that is exactly why we're way better off using UVD directly. No more waiting till AMD decides to make it usable. Reverse engineering anyone? ^_-
